Basement Waterproofing The Methods

A homeowner always feels that he could have done with a little more space in the house. The basement often remains abandoned full of dumped furniture and other scraps and we forget about it. This wastage of space can be stopped with basement conversion which is gradually becoming a popular fashion of using the basement and utilizing every inch of the extra space. Basement conversion enables one to have a new elaborate room without any additional construction. The structure of the house is not altered and no new building is added. At the same time, the problem of shortage of space is solved at costs much lesser than those of extensions.

Thorough basement waterproofing is essential before one starts decorating and using the area as a room. Basement walls generally need to withstand pressure because of the build-up of water around the room in the ground, as basements are situated below ground level. This pressure can result in cracks in the walls of the basement if proper basement waterproofing is not done. The cracks are menaces that allow water to seep into the room and create structural decay, damage and mould.

Basement waterproofing has both internal and external approaches. External waterproofing involves protection of both the floors and walls of the basement and ensures that absolutely no water can seep through into the basement. Waterproofing internally involves managing the flow of water that has already been allowed to enter the basement. It also includes leading the water to an exit point. The internal waterproofing method uses cavity membranes that form a gap between the internal and external walls within which seeped-through water is managed. With the help of cavity membranes, a neat living space can be created by concealing the contained water evacuation. Water is permitted to enter the building behind the internal wall. This water, in turn, reaches a drainage system that takes the water outside and away from the building.

Plasterboard or plaster is often applied on a cavity membrane’s internal wall. This enables the basement to be painted and adorned like just another room. The effect of a usable and habitable space is thus created while the cavity prevents the water damage.

One should not try basement waterproofing methods without proper knowledge and expertise. A professional waterproofing system must be installed in order to manage the underground water pressure and prevent the water from seeping into the basement. Polyurethane foam or spray is also often used. The foam plays the role of an extremely rigid sealant and is able to fix leaks and cracks around the basement walls and windows. Foam has strong weather-resistant properties and thus the treatment often remains effective for more than a decade.

As more and more homeowners consider basement conversion, adequate waterproofing becomes essential. If your basement suffers from the dangers of extreme and consistent water build-up, you should consider both the internal and external waterproofing solutions in order to ensure that no water damage takes place. Seeking the services of a competent professional is always advisable.
